AUDIO TECNICA ATW1128 RADIOMICROFONO
Known for outstanding audio quality and reliable performance, this full-rack professional wireless system includes a True Diversity VHF receiver and either a body-pack or handheld transmitter on a specific crystal-controlled frequency. Two antennas feed two completely independent RF sections on the same frequency; automatic logic circuitry continuously compares and selects the superior received signal, providing better sound quality and reducing the possibility of interference and dropouts. The receiver is designed to be mounted in a standard 19" rack (1U).
Features
True diversity reception and full FM deviation
Full FM deviation improves signal/noise ratio for greater headroom and dynamic range
Choice of 20 VHF frequencies
InvisibleLink circuitry delivers optimum sound quality
Ground-lift switch and adjustable squelch control
Balanced and unbalanced audio output jacks
Receiver mounts in a single 19" rack space
Dual-power battery-save switches on transmitters
ATW-T27 UniPakTM transmitter includes Super Hi-Z input that provides optimum load for guitar pickups
ATW-T28 handheld microphone/transmitter features a Hi-ENERGY dynamic element with superior internal shock mounting
